Antigravity Plugin for Claude Code

A local NotebookLM, multi-agent deep research, and 21 more commands — for Claude Code, powered by Google Antigravity (agy / Gemini 3.x), the official CLI that replaces the now-deprecated gemini-cli. Read whole folders of documents, transcribe audio & video, and research the web with citations — locally, offloading the heavy reading to Gemini so it barely touches Claude's context.

⚠️ Heads-up: gemini-cli shuts down on June 18, 2026

On May 19, 2026 Google announced at I/O that Antigravity CLI (agy) replaces Gemini CLI. After June 18, 2026 the old gemini-cli and Gemini Code Assist IDE extensions stop serving requests for AI Pro, Ultra, and free-tier users.[1] [2]

Google's stated reasoning: "Your workflows have simply outgrown those early days of 2025. You now require multiple agents communicating with each other to split up the work and solve complex problems." — Google Developers Blog

If you were using gemini-plugin-cc inside Claude Code, this plugin is your migration path. It targets agy directly. Enterprise users on Code Assist Standard/Enterprise licenses are not affected by the cutoff.

TL;DR — /agy:notebook <folder> | <objective> turns a folder of documents into a local NotebookLM: one objective-driven summary per document, a relevance INDEX.md, a cited RESUMEN_MAESTRO.md, a TIMELINE.md and an ENTIDADES.md — then /agy:notebook-ask answers questions over them with citations. /agy:deep-research <topic> runs multi-agent deep research: an evidence matrix + plan you approve, agy browsing each angle in parallel while Claude orchestrates adaptive rounds (--depth L<=2 / H<=4) plus a red-team pass, landing on a cited, applied recommendation. All the heavy reading and browsing runs in Gemini 3.x via agy, so it barely touches Claude's context. Plus audio & video transcription (/agy:transcribe, /agy:media), single-shot web research with citations, branded HTML reports, git-diff code review, doc-to-markdown, browser recording and more. No Node.js runtime. No MCP gymnastics. Twenty-two slash commands.

Install — the canonical repo (accept no look-alikes):

/plugin marketplace add MarcosNahuel/antigravity-plugin-cc
/plugin install antigravity@marcosnahuel-antigravity

Requires the agy CLI installed + a Google/Antigravity sign-in. Then /agy:setup.

What is this?

A Claude Code plugin that lets you delegate work to Google Antigravity CLI (agy) without leaving Claude Code.

• Antigravity CLI (agy) is Google's official agentic command-line assistant — released at Google I/O 2026 as the successor to gemini-cli. Rewritten in Go for speed, with native web-search grounding built into Gemini 3.x and multi-provider model support (Gemini, Claude, GPT-OSS).
• Claude Code is Anthropic's CLI for AI-assisted software engineering.
• This plugin bridges the two: from inside Claude Code, you invoke /agy:notebook, /agy:deep-research, /agy:research, /agy:report, /agy:ask, /agy:review, /agy:rescue, /agy:record, /agy:scrape, /agy:doc-to-md, /agy:design-review, or /agy:setup and the request gets handed to agy --print via a thin Bash forwarder.

The killer use case is deep web research with citations — Claude reasons over your repo, agy reasons over the live web. Each tool does what it's best at.

🗒️ Flagship: a local NotebookLM — /agy:notebook

Point it at a folder of documents (PDFs with text, scanned PDFs, images, docx) and an objective. agy (Gemini 3.x, multimodal) reads every document — OCR'ing the scans — and writes:

• one objective-driven summary per document (NN-<slug>.resumen.md, with relevancia 0–100),
• INDEX.md — every document ranked by relevance to your objective,
• RESUMEN_MAESTRO.md — a synthesis that answers your objective, citing each source document,
• TIMELINE.md — a chronological table of dated events, and
• ENTIDADES.md — extracted people, amounts, references and organizations, each with its source.

Then ask follow-up questions over the corpus:

/agy:notebook  ./docs  | objective: key decisions, owners, amounts, deadlines
/agy:notebook-ask  ./docs  | who owns the budget and when is it due?
→ "Owned by J. Doe; due 2026-07-08." (cites REP-0042)

Why it's different from pasting docs into a chat:

• Cheap on Claude tokens — Claude orchestrates; agy does all the document reading. You only read the two small final files.
• Grounded + cited — answers come only from your documents, with the source named.
• Incremental — re-running only re-summarizes new/changed documents (cache keyed by the objective).
• Model-routed — fast Flash for the per-doc sweep, Pro for the synthesis (/agy:model).
• Local & private — your documents never leave your machine + your own Gemini account.

It scales to real corpora: a 184-page scanned file is auto-split into page chunks so a single huge scan doesn't time out. Built for reading research papers, RFPs, contract sets, meeting-note archives, a book's chapters.
